Scabies in Infants: Series of 51 Cases.

We conducted a two-year retrospective evaluation of infants aged under two years with a confirmed, clinical, or suspected diagnosis of scabies in a healthcare center in Alicante (Spain) to determine possible factors associated with diagnostic delay and poor treatment response. We collected epidemiological, clinical, diagnostic, and treatment variables. After describing our findings as mean values and percentages, we compared categorical variables using the Student's -test and the Mann-Whitney U test, and we compared continuous variables with the Chi test and Pearson's correlation coefficient.

Cutaneous immune-related adverse events: incidence rates, risk factors and association with extracutaneous toxicity - a prospective study of 189 patients treated with checkpoint inhibitors at a Spanish tertiary care hospital.

Background: Clinicians are increasingly prescribing immune checkpoint inhibitors (ICIs) to treat cancer, but the real-world incidence, characteristics and risk factors of cutaneous immune-related adverse events (cirAEs) are unclear.

Objectives: To determine the incidence, features and risk factors of cirAEs and to measure their possible association with extracutaneous toxicity.

Methods: We conducted a prospective observational study in a Spanish tertiary care hospital, including people who started an ICI between March 2020 and May 2022.

A Case Series of 18 Congenital Haemangiomas: Clinical, Histological and Ultrasound Features, and their Relationship with Complications and Atypical Behaviour.

Recent studies have advanced our understanding of the clinical, histological and imaging characteristics of congenital haemangiomas (CHs), and have reported possible complications and atypical behaviour. The aim of this study is to describe the clinical, histological and ultrasound features of a series of CHs and to analyse their association with complications and atypical behaviour, with a view to providing diagnostic and management recommendations. The medical records, histology results and ultrasound images of all patients with CH diagnosed in the Dermatology Department of Alicante University General Hospital between 2006 and 2021 were retrospectively reviewed.

Cutaneous Metastases of Solid Tumors: Demographic, Clinical, and Survival Characteristics.

Background: Cutaneous metastasis (CM), while uncommon, is usually an indicator of poor prognosis. With cancer patients living longer, the incidence of CM has increased, which justifies its analysis.

Objectives: The objective of this study was to carry out a descriptive study of CM diagnosed for 18 years in a dermatology department of a tertiary care hospital and to assess the epidemiological, clinical, and histological variables that condition them, as well as data on their survival and prognosis.

Atypical pediatric presentation of lymphocytic thrombophilic arteritis: Diagnostic difficulties and recent nosological clarification.

A 4-year-old girl presented with a 2-month history of round, hypopigmented, slightly scaly patches measuring 1-6 cm and encircled by an erythematous halo, first appearing on the lower limbs then spreading to the whole body. Three biopsies were taken as the condition progressed, each showing a lymphocytic infiltrate affecting a medium-sized artery at the dermal-subcutaneous junction, with a concentric fibrin ring. These findings are characteristic of lymphocytic thrombophilic arteritis (LTA).

No SARS-CoV-2 antibody response in 25 patients with pseudo-chilblains.

Chilblain-like acral lesions have been identified in some coronavirus disease 2019 (COVID-19) patients. It has been suggested that these pseudo-chilblains could be a specific marker of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Most patients with these lesions have had negative polymerase chain reactions (PCRs), but some authors believe serology tests are likely to give positive results.

Teledermatology in paediatrics: Health-care impact on the early treatment of infantile haemangiomas.

Introduction: Teledermatology can solve diagnostic and therapeutic problems in paediatrics, for example in infantile haemangiomas (IHs) requiring early treatment with propranolol. This study aims to assess the impact of teledermatology following its implementation in a health area of Spain, specifically analysing its effectiveness in reducing the age of first propranolol treatment for IH.

Methods: This was a descriptive study of paediatric teledermatology from 2015 to 2018, studying age, sex, diagnosis, time and mode of resolution.

Presentation of pseudohypoparathyroidism and pseudopseudohypoparathyroidism with skin lesions: Case reports and review.

We report three cases of patients with pseudohypoparathyroidism or pseudopseudohypoparathyroidism. These diseases are considered GNAS inactivating mutation syndromes that are characterized by a diversity of alterations among which a particular phenotype and specific endocrine or ossification abnormalities may be found. These patients may present with hard cutaneous nodules, which can represent osteoma cutis.

Retronychia a little-known cause of paronychia: A report of two cases in adolescent patients.

Retronychia is a clinical condition resulting from embedding of the nail plate into the proximal nail fold. We report two adolescent girls, 14 and 16 years of age, with a history of chronic proximal paronychia of the great toe, one of them developing osteomyelitis. After failure of treatment with several systemic antibiotics, nail avulsion was performed, leading us to the diagnosis of retronychia and with rapid and complete resolution of symptoms in both cases.

Onychocryptosis: a long-term retrospective and comparative follow-up study of surgical and phenol chemical matricectomy in 520 procedures.

Background: Onychocryptosis or ingrown toenail is a common condition for which there are several treatment options. Surgical matricectomy (SM) is the classical procedure, whereas chemical matricectomy with phenol (CMP) is the most widely used nowadays.

Objectives: This study was designed to evaluate the success rate, postoperative comfort, postoperative complications, and patient satisfaction provided by each of these procedures.

Dermatoses in Latin American Immigrant Children Seen in a Universitary Hospital of Spain.

Over the past 10 years Spain has become an important immigrant receiver country as the proximity with Africa and the cultural facilities with Latino-American countries have made of Spain a very attractive place to settle down for immigrants. From 1st January 2007 to 31st December 2007, all the pediatric patients visits (0-14 years old) seen in the units of the Dermatology Section of the University General Hospital of Alicante (Spain) were prospectively recorded. During the study period 3,108 visits were recorded.

Neonatal Molluscum contagiosum: five new cases and a literature review.

Congenital or neonatal Molluscum contagiosum (MC) is an unusual infection, barely reported in the literature. In these patients a mechanism of transmission that is neither via contact or sexual transmission should be considered. We describe five cases of neonatal MC and review the cases already published to discuss the possible aetiopathogenic mechanism.

Abortive hemangiomas. Description of clinical and pathological findings with special emphasis on dermoscopy.

Infantile hemangiomas (IH) are the most commonly found benign neoplasia in childhood. Up to a third of IH may be present at birth and develop in 3 clearly defined stages. In their endothelial cells, IH express an erythocyte type glucose transport protein (GLUT-1), highly specific to this type of lesion, which enables them to be differentiated from other types of vascular lesions, including congenital hemangiomas (RICH or NICH) and capillary malformations.
